No, those people on the dance floor weren’t doing a bad version of the hokie pokie,
they were riding a 6.5 richter wave.
According to the Wall Street Journal and every news outlet in the world, which will begin reporting on this story until we’re all very very sick of it, the quake was just north of the small town of Ferndale, about 200 miles northwest of Sacramento. (This is not to be mistaken of the lesbian hotbed of Ferndale, Mich.)
The big shaker “Shook,” Ferndale volunteer fireman Manuel Enos told AFP, “windows broke or popped out of storefronts.”
The quake was felt as far away as San Francisco, though Californians could easily shake off the incident and attribute it to Earthquake weather — a phenomenon that doesn’t exist, but easily explains why people still live there.

i live in SF; in the geographic center of the city and didn’t feel a thing.
You’re joking? The news reports say it was felt there. It’s got to be felt there, or maybe, just maybe, a couple of reporters heard that a couple of cats ran away earlier this afternoon and that’s what they mean… I lived through the Northridge Quake (and lived in Venice Beach at the time) and know what it’s like to feel an earthquake. I moved shortly after that.
